(Krakatau | Volcano World | Oregon State University)

Explanation:

The island of Krakatau is located in Sunda Strait between Java and Sumatra. It is part of the Indonesian Island Arc. Volcanic activity is due to subduction of the Indo-Australian tectonic plate as it moves northward toward mainland Asia. The Krakatoa island is found to be about 3 miles wide and 5.5 miles long (9 by 5 kilometers). As at the time of this eruption in 1883, the region was part of the Dutch East Indies; it’s now part of Indonesia. Location: Krakatoa, Anak Krakatau Island, Pulau, South Lampung Regency, Lampung, Indonesia, Asia.

In August 1883, the eruption of Krakatoa, (or Krakatau), was one of the most deadly volcanic eruptions of modern history ever recorded. It is estimated that more than 36,000 people died. The deaths recorded were as a result of the thermal injury from the blasts. Also, the victims were of the tsunamis that followed the fall of the volcano into the caldera below sea level. The temperatures dropped all over the world and the climate was affected because the eruption was so terrible.
